I listened to a lot of shortwave broadcasts and sent SWL reports or cards to some of them, such as KBS, Vatican Radio, and Life Light. However, I always wanted to receive a verification card from our mysterious neighbor, North Korea (to compensate for the regret of not having P5 radio). I listened to VOK Korean Voice several times, but due to the pandemic or other reasons, communication between North and South Korea has been cut off. Recently, I learned that the land and sea postal routes between North and South Korea have been restored, so I quickly sent out my SWL cards and reports.
